ISMAn exclusive Mavic patented concept, ISM involves the machining of the lower bridge of the rim between each spoke hole to create a light and rigid rim without reducing the durability of the rim. This reduces the weight by approx. 40 grams making climbing easier and giving a low inertia for effortless acceleration.

SUPSoudé Usiné Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish to give a stronger and smoother joint with superior wheel balance that eliminates braking shudder.
